The sustainable improvement of maize productivity and smallholders’ incomes to contribute food security is the objective this study carried out over two consecutive years (2020 2021) at University Lomé Agronomic Experiment Station. experiment was set up in a split-plot design, composed sixteen (16) treatments three (03) replicates each. Four varieties: Ikenné (V1) Tzee (V2), Sotubaka (V3) Samma...

milkthistle (silybum marianum l.) is a rangeland medicinal plant growing wild in different locations in iran. in the present research work, the effect of n, p and k in their different proportions of n0p0k0, n100p100k50, n150p150k100 and n200p200k150 kgha-1 as compared with control (no fertilizer application) on the plant's growth was put to test. suc variables as plant height, no. of capit...

yield, harvest index and morphological characters of 13 spring cultivars of rapeseed were evaluated in 2007 growing season at agriculture and natural resources research station of torogh, mashhad. these cultivars were from three rapeseed species belonged to brassica napus, brassica rapa and brassica juncea. experimental design was randomized compelet block with four replication. result showed t...

studies on crop improvement of saffron (crocus sativus l.) can play an important role in development of this native crop. in this context, an experiment was conducted at agricultural research station, ferdowsi university of mashhad, iran, as a factorial based on randomized complete block design with three replications, during 2005-2010 years. first studied factor was planting pattern of saffron...

The adaptive responses of crop genotypes and patterns of genotype x location (G x L) interaction are important to crop improvement as they are the basis for selection for specific adaptation and for elucidation of the causes of G x L interaction. Their legitimate assessment, however, requires yield data for the test genotypes for a large number of sites and over multiple years. Such data are se...

low cereal and legumes yields and their rwp index are mainly due to poor distribution of rainfall and poor agronomic management practices. rainfed barley yield and rain water productivity (rwp, defined as rainfed grain yield divided by the total crop season annual rainfall water) in the dry farming are considerable by topography and latitude. yield data, rainfall, altitude and latitude of 182 p...
